Red Sea Reefer (RSF) 250 V3 Sump Refugium Water Volume

ChadmRoman · Jun 4, 2019

Hi all, researching the RSR 250, and want to make sure I have the correct numbers to calculate the refugium water volume. Using the attached dimension sheet, I came up with the following:

Main refugium in cm - 16.3 x 25.6 x 23.5 = 9.81 liters
If incorporating the drain cup section - 21.4 x 21.9 x 23.5 = 11.01

Thinking about going full Triton method on my next build. If my numbers are correct (short by 5 liters), I would still need to upgrade the sump.

Looking for confirmation on the above numbers please.

The RS site says the Reefer 250 has 11 gallons in the sump.

Under the lid for overflow box, it should have a sticker that says tank volume and total water volume. The difference is sump + ATO.

My label says the sump is 11 gallons as mentioned in my post above and the reservoir is 2.1 gallons.

Decided to go the route of used, bought a RSR250 v2 second hand, and purchased The RSR 250 Crystal Reef Aquatics triton sump during their 10% off sale. Currently everything’s sitting in the garage waiting for my funds to replenish to purchase the remaining items to build this out. Thinking by the end of the year, I should have a fully functioning triton setup.

Thanks for asking.
